Abstract

A process for curing a polymeric article formed from a fiber material inpregnated with uncured phenolics, unsaturated polyesters, epoxides, or silicones. The process involves placing the uncured article into a non-gas tight pressure chamber, packing the chamber with lubricated beads, and heating the article under pressure. Additionally, fiber-reinforced thermoplastics may be heat shaped in the presence or absence of a mold.
